To clarify, this is about training your phone to recognize only "Hey Siri" as spoken by you, as opposed to letting you personalize your trigger phrase to something other than "Hey Siri".

Yeah, they don't want to give users too much control; Siri is an important brand by itself and Apple doesn't want people going around skipping it.

  It's too bad, because I sure wish I could make the homepod use a different phrase. The homepod knows to activate when I say hey siri, but my friends phone activates instead of the homepod whenever they say 'hey siri' about %50 of the time.

  At least Siri is easy to say internationally. I never manage to use the proper accent when I say "Okay Google".

  The non-cynical viewpoint would be that "Hey Siri" is an easy phrase to detect because of how it's said, which isn't really that similar to many other phrases.

    “Hey Siri” actually a pretty challenging trigger phrase. It’s short (few phonemes), and it’s phonetically confuseable with phrases like “Hey Serial is out” (could be “Hey Siri all is out”).

  Yes. In this case, the selection of a wake word ("Alexa") or phrase ("Hey Siri" or "OK Google") is driven primarily by performance (i.e., reduction of false accepts & false rejects). The folks designing these products know that, even though customers say that they'd like to customize the wake word or phrase, if the actual performance is significantly worse, those customers will not be happy. We experimented with this extensively.

    But it's infuriating when you don't want to use the phrase and/or want to have a secret phrase. Better would be to allow customers to choose their own phrase and give immediate feedback, during setup, on how good it's likely to be.

      There's such a difference, and it's so hard to find really high-performing ones, that you would be constantly telling customers, "that won't work well"... We considered literally thousands of potential words. We also really didn't want anything like "hey" or "ok" to be required. Note how long it took for "Computer" to be available - and you can imagine how many of us wanted that. I think it gives an idea of the difficulty.

    If you can share, what kind of variation in F1 score were you seeing between different trigger words? I'd expect even within a single product family (i.e. Alexa/Echo/Amazon/Computer) there's probably significant variation. I'd also be interested in the differences between a collectively-optimized wake word (without personal training) and one which the user personally trains against their voice à la the parent article. To what extent does that personal training supplement/supplant (or fail to do so) the "good enough for everyone" wake word kernels?

      Nothing I can share, unfortunately.
